Convert 3/4 into a percentage.
To convert a fraction to a percentage, multiply by 100. (3/4) × 100 = 75%.
What is 20% of 150?
20% is equivalent to 0.2. Multiplying 150 by 0.2 gives 30.
Solve: 12 × 12 ÷ 4
Following DMAS, 144 ÷ 4 = 36.
Which fraction is the largest?
For unit fractions, the one with the smallest denominator has the largest value.
What is 0.1 + 0.01 + 0.001?
Align the decimal points and add: 0.100 + 0.010 + 0.001 = 0.111.
If a dozen eggs cost 120, what is the price of 3 eggs?
One egg costs 120/12 = 10. Therefore, 3 eggs cost 30.
450 is what percent of 900?
Since 450 is exactly half of 900, it is 50%.
Solve: 1/2 + 1/4
Find a common denominator: 2/4 + 1/4 = 3/4.
Find the product of 0.02 and 7.
2 × 7 = 14. Adjust for two decimal places to get 0.14.
What is 25% of 80?
25% is 1/4 of a number. 80 divided by 4 is 20.
If you subtract 199 from 1000, you get:
1000 - 200 is 800, then add 1 back to get 801.
Divide 0.8 by 0.2.
0.8 / 0.2 is the same as 8 / 2, which equals 4.
Convert 0.125 to a fraction.
0.125 is 125/1000, which simplifies to 1/8.
What is the sum of the first five prime numbers?
The first five primes are 2, 3, 5, 7, and 11. Their sum is 28.
If 10% of a number is 50, the number is:
If 1/10 of a number is 50, the full number is 50 × 10 = 500.
88 ÷ 0.11 =
Remove the decimal by multiplying both by 100: 8800 ÷ 11 = 800.
What is 15 × 6?
15 multiplied by 6 equals 90.
2/5 of 100 is:
Divide 100 by 5 to get 20, then multiply by 2 to get 40.

What is the value of sin 30°?
According to the standard trigonometric table, sin 30° is 0.5 or 1/2.
The ratio sin θ / cos θ is equal to:
By definition, the tangent of an angle is the ratio of sine to cosine.
sin² θ + cos² θ is always equal to:
This is the fundamental Pythagorean identity in trigonometry.
What is the value of cos 90°?
At 90°, the x-coordinate on a unit circle is 0, so cos 90° = 0.
In a right-angled triangle, sin θ is defined as:
Sine is the ratio of the side opposite the angle to the longest side.
The value of tan 45° is:
At 45°, the perpendicular and base of a right triangle are equal, making the ratio 1.
1 + tan² θ is equal to:
This is one of the three primary Pythagorean identities.
sec θ is the reciprocal of:
Secant is defined as 1 divided by the cosine of the angle.
What is the value of sin 90°?
The sine function reaches its maximum value of 1 at 90°.
csc θ is equal to:
Cosecant is the reciprocal ratio of the sine function.
The value of cos 60° is:
In a 30-60-90 triangle, the adjacent side to the 60° angle is half the hypotenuse.
If tan θ = 1, then θ is:
The tangent of 45° is 1 because the opposite and adjacent sides are equal.
What is cot 90°?
cot 90° = cos 90° / sin 90° = 0 / 1 = 0.
The value of sin 45° is:
For an angle of 45°, the sine value is approximately 0.707 or 1/√2.
1 + cot² θ is equal to:
This identity relates the cotangent and cosecant functions.
If sin θ = 3/5, what is cos θ?
Using the Pythagorean triplet (3, 4, 5): 3² + 4² = 5².
What is the value of tan 60°?
tan 60° = sin 60° / cos 60° = (√3/2) / (1/2) = √3.
cos² 30° is:
Since cos 30° = √3/2, squaring it gives (√3)² / 2² = 3/4.
The range of sin θ is:
The sine function oscillates between a minimum of -1 and a maximum of 1.
tan θ is not defined at:
At 90°, cosine is 0. Since tan = sin/cos, it results in division by zero.
