It could be 5(8*7)4* it could be ok
Answer: 7 and 1 sevenths
Step-by-step explanation:
turn them to improper fractions and you get 40/7 x 5/4
then cancel out to make it easier it would then look like this 10/7 x 5/1
now solve
10 x 5 is 50
7 x 1 is 7
50/7 is your answer but you need to change it by solving 50 divided by 7
your final answer is 7 and 1 sevenths
