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, 40.9, and 38 miles. Their solutions are shown. 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?
Bruno is correct. When going from a larger unit to a smaller unit you need to divide.

We are given number of miles the 3 bike trips they took last month = 45.7, 40.9, and 38 miles.

Sam and Bruno were computing how many kilometers.

Also one kilometer equals 0.621 miles.

From this we can see than 1 kilometer is smaller unit and a mile is a larger unit.

In order to convert number of miles into kilometers, we need to divide each number of mile by 0.621 miles.

We always divide a larger value by a smaller value to get the smaller unit.

Therefore,

Bruno is correct. When going from a larger unit to a smaller unit you need to divide.

Find the sum

2/8 + 3/9

Answers

at first find common denominator - is 72 so we need multiply first fraction by 9 and second fraction by 8
$(2)/(8)+ (3)/(9)$ = $(2*9)/(8*9)+ (3*8)/(9*8)$ = $(18)/(72)+ (24)/(72)= (42)/(72)= (6*7)/(6*12)= (7)/(12)$

STEP Δ1Δ find the least common denominator/multiple of 8 and 9. 2/8= 18/72. 3/9= 24/72. Step 2 Add. 18+24= 42. Step 3 Simplify. 42/62= 21/36= 7/12. Once you reach 7/12, you can no longer simplify. So, your final answer is 7/12, or seven twelths (even though that not how you spell it). Hope this helps ;). Thank you and have a super awesome day.
