Please help me I often have trouble with these kind of questions ever since sixth grade How to subtract 32/10 and 7/5

18/10 or 1 4/5

Step-by-step explanation:

32/10 - 7/5

Remember that in order to subtract fractions, you always need to have the same denominator.

The denominator of 32/10 is 10.

The denominator of 7/5 is 5.

Are the denominator the same? In other words, are 10 and 5 equal? No, so now we need to make the denominator the same so that they are equal. To do that, find the LCM of 10 and 5.

List the LCM:

10: 10, 20, 30

5: 5, 10, 15, 20

Do you see any numbers in the list of the two numbers that are the same? Yes, 10 and 20. But since we are finding the LCM (Least common multiple), we need to use the smallest common multiple, which is 10.

Now that we found the LCM, make the denominator of 7/5 the same as 32/10.

To do that, just multiply the numerator and the denominator of 7/5 by 2; 7 times 2 is 14, 5 times 2 is 10. The final fraction should be 14/10.

Do 14/10 and 32/10 have the same denominator now? Yes, right?

Now, it’s the simple part. We now have the expression, 32/10 - 14/10.

Just subtract across, but keep the 10 as the denominato. 32 - 14 is 18. Keep the denominator 10, and you get 18/10 as your answer.

Therefore, 18/10 or 1 4/5 (if turned into a mixed fraction and simplified) is the answer. Hope this helps!
