0.4 equals blank over 10 and equals blank over 100. what goes in the blanks

for the first one, 4.

then it reads .4 equals 4/10 and..

8+2=10

To solve this problem, we can use fractions.

To determine what 0.4 equals over 10, we can write it as a fraction:

0.4/10

To simplify this fraction, we divide both the numerator and denominator by their greatest common divisor (GCD), which in this case is 0.2:

0.4 ÷ 0.2 = 2
10 ÷ 0.2 = 50

So, 0.4 over 10 is equal to 2/50.

Now, let's find what 0.4 equals over 100. We can write it as a fraction:

0.4/100

Following the same process as above, we divide both the numerator and denominator by their GCD, which is 0.02:

0.4 ÷ 0.02 = 20
100 ÷ 0.02 = 5000

Therefore, 0.4 over 100 is equal to 20/5000.

In summary:
- 0.4 over 10 = 2/50
- 0.4 over 100 = 20/5000
