Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cup

Anton [14]

Answer:

Let x be the total number of cupcakes.

Chocolate chips =

$\frac{2}{3} x$

Strawberry =

$\frac{1}{4} \times \frac{1}{3} \\ = \frac{1}{12} x$

Vanilla =

$x - \frac{2}{3} x - \frac{1}{12}x \\ = \frac{1}{3} x - \frac{1}{12} x \\ = \frac{1}{4} x$

given

$\frac{1}{4} x = 90$

$x = 90 \div \frac{1}{4} \\ = 90 \times 4 \\ = 360$

a)Number of Chocolate chip Cupcakes =

$\frac{2}{3} \times 360 \\ = 240$

b)Number of Strawberry cupcakes =

$\frac{1}{12} \times 360 \\ = 30$

They need 1 1/2 cups of sugar. How many 1/4 cups should they measure

tekilochka [14]

The correct answer I got was 22 cups. 11/2 ÷ 1/4 is how you set it up. Then, you do KCF which stands for keep, change, flip. So, your new expression is 11/2 × 4/1. You cross reduce 4 & 2 which makes the new expression 11/1 × 2/1. 11 times 2 is 22/1 which still equals 22.
