If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.

Answer:
-$150
Step-by-step explanation:
Given:
(I - E) / 12
Where,
I = total income
E = total expenses
I = $52,000
E = $53,800
(I - E) / 12
= (52,000 - 53,800) / 12
= -1,800 / 12
= -150
-$150 shows that Mr. Engle's total expenses exceeds his total income per month with an average of $150
(2a+2)(4a+4)
