Question

find x in 5x23 which is a multiple of 3

Answer 1

Answer:

2

Step-by-step explanation:

5+X+ 2+3= 10+X

if a number is divisible by 3 then the sum of digits must be divisible by 3

to make 10+X divisible by three we must add 2 in 10 ,since 12 is nearest to the 10 that is divisible by 3

Answer 2

5X = 24

X IS THE MULTIPLE OF 3

5X = 24÷3

5X = 8

X = 8÷5 = 1.6
