7 : 0.1 = 7 : 10 1 = 7 × 1 10 = 7 × 10 = 70
c h ec k : 0.1 × 70 = 7
Assume that the number we are looking for is x
one tenth is interpreted into 10 1
Now, we know that one tenth of the number is 7, this means that:
10 1 * x = 7
Solve for x by multiplying both sides of the equation by 10, we get:
10 1 * x * 10 = 7 * 10
x = 70
Hope this helps :)
7 is one tenth of the number 70. We found this by setting up the equation 10 1 × x = 7 and solving for x . Thus, x equals 70.
