Grade: 8-a Lesson: S1-L5 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Add \$5 35/25 + 8 28/30\$. |
|
2 |
Step |
We change the mixed fractions into improper fractions. |
\$160/25 + 268/30\$ |
3 |
Step |
we need to reduce the fraction. |
\$32/5 + 134/15\$ |
4 |
Step |
Now Least Common Multiple (LCM) between the denominators. |
L.C.M 5, 15 = 15 |
5 |
Step |
Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. |
\$ ((32\times 3 )+(134\times1))/15\$ |
6 |
Step |
Add the numerators and keep the denominator the same. |
\$(96 + 134)/15\$ = \$230/15\$ |
7 |
Step |
Divide the numerator with the denominator. |
\$230\div15\$ |
8 |
Step |
You will get values of quotient (q)and remainder( r ). |
q=15,r=5 |
9 |
Step |
\$"Mixed fraction"\$ = \$"Whole number" + "Numerator" /"Denominator"\$ |
\$15 5/15\$ |
