A carpenter sawed a board into 5 equal pieces each 3 1/8 inches long. How long was the board?

1 answer:

4 0

Hi there! To solve this question, we can just simply multiply 3 1/8 and 5, because we're looking for the total length of the board, before it was cut into 5 equal pieces. To multiply fractions, just do it straight across. Numerator * numerator / denominator * denominator. 3 1/8 as a mixed number is 25/8 and 25/8 * 5/1 is 125/8 or 15 5/8 in mixed number form. There. The board was 15 5/8 inches long. The answer is D.

Answer:

92.5%

Step-by-step explanation:

shaded squares/total squares = 185/200

simplify:

(185/5)/(200/5) = 37/40

37/40= 35/40 + 2/40

32/40 + 5/40 = 4/5 + 1/8

4/5 + 1/8 = 0.8 + 0.125

0.8 + 0.125 = 80% + 12.5%

80% + 12.5% = 92.5%
