Answer:
1 ⁷/40
find lcm of the denominators (the bottom numbers) 8&5
lcm is 40
ask your self how many times can 40 be divided by 8? 5 times good job .
so you multiply top & bottom of 3/8 by 5
3×5=15 8×5=40
we now get a new fraction 15/40
ask your self how many times can 40 be divided by 5? 8 times very good !
so you multiply top & bottom of tht fraction by 8
4×8=32 5×8=40
new fractions are 15/40 & 32/40
we did all of that to get fractions with the same denominator because fractions with like denominators are easy to add you add the top numbers & keep the bottom.
15+32=47
47/40 now this fraction can be simplified to a mixed number
ask yourself how many times can 40 go into 47 ? one time
40×1 =40 & there are 7 remainders & you just keep the denominator the same .
1 ⁷/40
