What is 3 1/4- 1 7/8 but i need to do it by renaming it so i need help
1.375?
3 + 2/8 - 1 - 7/8
= 2 + 10/8 - 1 - 7/8
= 1 + 3/8
1 3/8
==============
check
===================
1 3/8 + 1 7/8 = 2 10/8 = 3 2/8 = 3 1/4
whew !
3 1/4 = 3.25
1 7/8 = 1.875
3.25-1.875=1.375
To subtract mixed numbers like 3 1/4 - 1 7/8, you need to first rename the mixed numbers into improper fractions. Then you can easily subtract them. Here's how you can do it step by step:
Step 1: Rename the mixed numbers as improper fractions:
3 1/4 = (3 × 4 + 1) / 4 = 13/4
1 7/8 = (1 × 8 + 7) / 8 = 15/8
Step 2: Now, you can subtract the improper fractions:
13/4 - 15/8
Step 3: Since the denominators are not the same, you need to find a common denominator. The least common multiple (LCM) of 4 and 8 is 8, so you can rewrite the fractions with a common denominator:
(13/4) × (2/2) = 26/8
(15/8)
Step 4: Subtract the numerators while keeping the denominator the same:
26/8 - 15/8 = (26 - 15) / 8 = 11/8
Step 5: The result, 11/8, is still an improper fraction. You can simplify it by dividing the numerator by the denominator:
11 ÷ 8 = 1 remainder 3
So, the final answer is 1 3/8.
Therefore, 3 1/4 - 1 7/8 is equal to 1 3/8.
