Sam and Bruno were computing how many kilometers they rode in the 3 bike trips they took last month. In order, they rode 45.7, 4

0.9, and 38 miles. Their solutions are shown. Sam's Solution Bruno's Solution 45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 times 0.621 = 77.38 kilometers. 45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64 kilometers. If one kilometer equals 0.621 miles, which is the best solution to find the total number of kilometers they rode? Why is it correct?

Answer:

Correct solution:

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64

Step-by-step explanation:

they rode 45.7, 40.9, and 38 miles

= (45.7 + 40.9 + 38) miles

= 124.6 miles

Convert 124 .6 miles to kilometers

1 kilometer = 0.621 miles

124.60 miles = 124.60 / 0.621

= 200.64 kilometers

This is the correct solution because he divided 124.60 miles by 0.621

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64

What is the area of the figure? A rectangle is cut out of a large rectangle. The larger rectangle has a base of 6 yards and heig
masya89 [10]

Small one: 18 and 1-thirds yards²  Large one: 43.5 yards²

Step-by-step explanation:

Area of rectangle= base*height

Large one: base = 6, height= 7.25 (7 and 1-fourth)

Area= 43.5yards²

Small one: base = 3(2/3 or 2-thirds), height= 5

change the mixed fraction 3(2/3) to 11/3

area= 11/3 * 5 = 55/3

change to mixed fraction which = 18(1/3)
