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 |
Formula: |
\$"Mixed fraction"\$ = \$"Whole number" + "Numerator" /"Denominator"\$ |
\$15 5/15\$ |

SumUp |
Can you summarize what you’ve understood in the above steps? |
|
11 |
Choice.A |
\$16 3/15\$ is incorrect because the simplified fraction is \$2 5/15\$, not \$3 5/15\$ |
\$16 3/15\$ |
12 |
Choice.B |
The correct answer represents the proper simplified fraction for the given sum |
\$15 5/15\$ |
13 |
Choice.C |
\$16 2/15\$ is incorrect because the simplified fraction is \$2 5/15\$, not \$2 5/15\$ |
\$16 2/15\$ |
14 |
Choice.D |
\$16 1/15\$ is incorrect because the simplified fraction is \$2 1/15\$, not \$3 1/15\$ |
\$16 1/15\$ |
