Two fifths of a number equals-24 find the number

2/5 *x=-24

x=unknown number

2/5x=-24

Multiply both sides by 5/2

2/5(5/2)x=-24(5/2)

Cross out 2/5 and 5/2, divide by 5 and 2 . Then becomes x.

Cross out  -24 and 2, divide by 12.

-12*5=x

x=-60

x=-60

the correct answer is 5 6 and 7

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
