1 5/6 + 1/2
= 11/6 + 3/6
= 14/6 answer
Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
