There are 24 men and 36 women in a choir.

Molodets [167]

Answer:

Step-by-step explanation:

Total members in the choir = 24 + 36 = 60

a) Percentage of men = $\frac{24}{60}*100$

= 4 * 10 = 40%

b) Percentage of women = 60%

c) Number of men =24 + 10 = 34 men

Number of women = 36 + 10 = 46

Total = 34 + 46 = 80

Percentage of men = $\frac{34}{80}*100= 42.5$ %

Percentage of women = (100 - 42.5)% = 57.5%

Mrs Ruiz has 11/12 yard of string to hang 3 banners. She uses the same length of string to hang each banner. How much string doe

n200080 [17]

She uses 11/36 yards of string for each.

In this problem, you're dividing the amount of string by the number of banners, so 11/12 ÷ 3. To do this though, it's easiest to convert the 3 into a fraction. After you do this, you're left with:

11/12 ÷ 3/1

When dividing fractions, you flip the second fraction upside down and change the operation to its opposite, which gives you:

11/12 × 1/3

Then you just multiply across. 11×1=11 and 12×3=36, so you're left with 11/36 yards of string.
