Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Subtract \$8 6/40 - 6 4/30\$. |
|
2 |
Step |
Given Fraction. |
\$8 6/40 - 6 4/30\$ |
3 |
Step |
We change the mixed fractions into improper fractions. |
\$326/40 - 184/30\$ |
4 |
Step |
We need to reduce the fraction |
\$163/20 - 92/15\$ |
5 |
Step |
Now, take the LCM of the denominators. |
LCM of 20,15 is 60 |
6 |
Step |
Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. |
\$((163\times3)-(92\times4))/60\$ |
7 |
Step |
Subtract the numerators and keep the denominator the same. |
\$(489 - 368)/60\$ |
8 |
Step |
After subtracting we get. |
\$121/60\$ |
9 |
Step |
Divide the numerator with the denominator. |
\$180\div60\$ |
10 |
Step |
You will get values of the quotient(q) and remainder(r). |
q= 2 r =1 |
11 |
Step |
\$"Mixed fraction"\$ = \$"Whole number" + "Numerator"/"Denominator"\$ |
\$ 2 1/60\$ |
