5 0

Answer:

Step-by-step explanation:

b/g=5/4

b=5g/4, we are also told b=g+3, since b=b we can say

5g/4=g+3, multiply each side by 4

5g=4g+12, subtract 4g from each side

g=12, and since b=g+3

b=12+3=15

So there are 15 boys and 12 girls.

A recipe requires 1/5 cup of sugar and 1/2 cup of flour. How many times as much flour is required for the recipe as sugar?
Damm [24]

Answer:

2.5 times

Step-by-step explanation:

To compare the two quantities, find a common denominator.

1/5 is 2/10 of sugar.

1/2 cup of flour is 5/10 of flour.

There is almost 3 times as much flour as sugar. 5/ 2 = 2.5. It is 2.5 times as much.
