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
