The process in the linked math website will help you do both problems.
70 and 5%
To find out what number 42 is 60% of, we can use the following formula:
(Number we are looking for) = (Given number) / (Percentage as a decimal)
Let's insert the values:
(Number we are looking for) = 42 / 0.60
Now we will divide 42 by 0.60:
(Number we are looking for) = 70
Therefore, 42 is 60% of 70.
To find out what percent of 400 is 20, we can use the following formula:
(Percentage we are looking for) = (Given number / Total number) x 100
Let's insert the values:
(Percentage we are looking for) = (20 / 400) x 100
Now we will divide 20 by 400 and then multiply the result by 100:
(Percentage we are looking for) = 0.05 x 100
Therefore, 20 is 5% of 400.
To find the number that 42 is 60% of, we can set up an equation:
42 = 0.60 * x
To solve for x, we can divide both sides of the equation by 0.60:
42 / 0.60 = x
x ≈ 70
Therefore, 42 is 60% of 70.
To find what percent 20 is of 400, we can set up another equation:
20 = (x/100) * 400
To solve for x, we can divide both sides of the equation by 400 and then multiply by 100:
(20 / 400) * 100 = x
x ≈ 5
Therefore, 20 is approximately 5% of 400.
