To convert the fraction 3/4 to a decimal, divide the numerator (3) by the denominator (4). Performing the division gives 0.75, which represents three-quarters of a whole. This decimal indicates that 3 out of 4 parts are being considered, confirming that 3/4 equals 0.75.

To find 25% of 80, you can multiply 80 by 0.25 (which is the decimal equivalent of 25%). Calculating this gives 80 × 0.25 = 20. Thus, 25% of 80 is 20.

To convert 0.6 to a fraction, recognize that 0.6 is equivalent to 6/10. Simplifying 6/10 by dividing both the numerator and denominator by their greatest common divisor, which is 2, results in 3/5. Thus, 0.6 as a fraction in simplest form is 3/5.

To find what percentage 15 is of 60, divide 15 by 60, which equals 0.25. To convert this decimal to a percentage, multiply by 100, resulting in 25%. Thus, 15 represents 25% of 60.

To convert a percentage to a decimal, divide the percentage by 100. For 45%, this means 45 ÷ 100, which equals 0.45. This conversion shifts the decimal point two places to the left, resulting in the decimal form of the percentage.

To compare 2/5 and 0.35, convert 2/5 to a decimal by dividing 2 by 5, which equals 0.4. Since 0.4 is greater than 0.35, 2/5 is the larger value.

1/4 is equivalent to 0.25 in decimal form. When you add 0.25 to 0.25, the sum is 0.5. Additionally, 0.5 can be expressed as 1/2 in fractional form. Therefore, both 0.5 and 1/2 represent the same value, making "Both a and b" the correct answer.

To find the sale price of the shirt, first calculate the discount amount by multiplying the original price ($40) by the discount percentage (30%). This gives a discount of $12. Subtract this discount from the original price: $40 - $12 = $28. Thus, the sale price is $28.

To convert a fraction to a percentage, divide the numerator by the denominator and then multiply by 100. For 5/8, divide 5 by 8 to get 0.625, and then multiply by 100 to obtain 62.5%. This represents the fraction as a percentage of the whole.

To convert the fraction 7/10 into a decimal, divide the numerator (7) by the denominator (10). This results in 0.7, which represents seven tenths in decimal form. Each digit after the decimal point indicates a fraction of ten, making 0.7 the correct representation.

To find the number, let it be represented as \( x \). Since 20% of \( x \) equals 12, we can express this as \( 0.2x = 12 \). By dividing both sides by 0.2, we get \( x = \frac{12}{0.2} = 60 \). Thus, the number is 60.

To find the result of subtracting 0.35 from 5/8, first convert 5/8 to a decimal, which is 0.625. Then, perform the subtraction: 0.625 - 0.35 equals 0.275. This shows that the difference between these two values is 0.275.
