Explanation:

Step1: Find 10% of 70

To find a percentage of a number, we convert the percentage to a decimal (by dividing by 100) and then multiply by the number. For 10%, we have \( 10\% = \frac{10}{100}=0.1 \). Then we multiply by 70: \( 0.1\times70 = 7 \).

Step2: Find 40% of 70

For 40%, we convert it to a decimal: \( 40\%=\frac{40}{100} = 0.4 \). Then multiply by 70: \( 0.4\times70=28 \).

Answer:

10% of 70 is 7.
40% of 70 is 28.
