Explanation:

Step1: Convert percentage to decimal

To find 70% of 40, first convert 70% to a decimal. 70% is equivalent to $0.7$ (since $70\%=\frac{70}{100} = 0.7$).

Step2: Multiply by total number of problems

Now, multiply this decimal by the total number of problems (40) to find the number of correct problems. So we calculate $40\times0.7$.
$40\times0.7 = 28$

Answer:

28
