Question

) A student earned a grade of 60% on a math test that had 20 problems. How

many problems on this test did the student answer correctly​

Answer 1

Answer:

12

Step-by-step explanation:

Let's divide the % into two parts I.e,

60%=50%+(3×10%)

Now, 50% of the number 20 should be calculated

Just divide the number by 2 to get 50% of any number..

20÷2=10

10% of 20 :

Place the decimal point after the units place of a number to get 10% I.e

2.0

Now 10 +(2×1)=10+2=12

80% of 20 is 12.
