Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Add \$4 50/15 + 6 45/20\$ |
|
2 |
Step |
We change the mixed fractions into improper fractions |
\$110/15 + 165/20\$ |
3 |
Step |
we need to reduce the fraction |
\$22/3 + 33/4\$ |
4 |
Step |
Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator |
L.C.M 3, 4 = 12 |
5 |
Step |
Add or subtract the numerators and keep the denominator the same |
⇒ \$ ((22 \times 4 ) + (33 \times3))/12\$ |
6 |
Step |
Divide the numerator with the denominator |
⇒ \$(88 + 99)/12\$ ⇒ \$187/12\$ |
7 |
Step |
You will get values of quotient (q) and remainder( r ) |
q = 15, r = 7 |
8 |
Formula: |
\$"Mixed fraction"\$ = \$"Whole number" + "Numerator" /"Denominator"\$ |
\$15 7/12\$ |
