B. 36 To find the number of sheets that Laura is going to fill with her stamps, we first have to find the total number of stamps. If she has 24 stamps EACH from 6 countries, to get the total, we will multiply 24 x 6 = 144 total number of stamps.
to see how many sheets she will fill we will DIVIDE the total number of stamps by 4 because that is the number she can fit onto One display sheet. 144 ÷ 4 = 36 36 sheets will be used to put four stamps each from a total of 144 stamps.
This can be determined by following writing equal ratios that represent a word problem. Then, the denominator must be divided from the numerator to get the unit rate/ meters per second.
