Jose washed 3/10 of the windows on his house Saturday morning. He washed another 3/5 of the windows that afternoon. What fractional parts of the windows are not washed
3/10?
No. Please try again.
To find out the fractional parts of the windows that are not washed, you need to subtract the total fraction that Jose washed from 1.
In this case, Jose washed 3/10 of the windows in the morning and 3/5 in the afternoon. To find the total fraction he washed, we need to add these two fractions:
3/10 + 3/5
To add these fractions, we need to find a common denominator. The least common multiple of 10 and 5 is 10. So, we can rewrite the fractions with a common denominator of 10:
(3/10) + (6/10)
Now we can add the numerators together:
3 + 6 = 9
The denominator stays the same:
9/10
So, Jose washed 9/10 of the windows. To find the fractional parts that are not washed, subtract this fraction from 1:
1 - 9/10
To subtract fractions, we need a common denominator. The denominator of 9/10 is already 10, so we can write 1 as a fraction with a denominator of 10:
10/10 - 9/10
Now we can subtract the numerators:
10 - 9 = 1
The denominator stays the same:
1/10
Therefore, the fractional part of the windows that are not washed is 1/10.
