Explanation:

1. 35 is 50% of what number?

Step1: Convert percentage to decimal

50% = 0.5

Step2: Use formula \( Whole=\frac{Part}{Percentage} \)

\( Whole = \frac{35}{0.5}=70 \)

Step1: Convert percentage to decimal

15% = 0.15

Step2: Use formula \( Whole=\frac{Part}{Percentage} \)

\( Whole = \frac{6}{0.15}=40 \)

Step1: Convert percentage to decimal

5% = 0.05

Step2: Use formula \( Whole=\frac{Part}{Percentage} \)

\( Whole = \frac{13}{0.05}=260 \)

Answer:

70
