|---|---|---|---|
1 |
Problem |
What will be the missing number in the given equivalent fraction \$8/?\$ = \$72/90\$. |
|
2 |
Hint |
Cross-multiplying involves multiplying the numerator of one fraction by the denominator of another fraction. |
|
3 |
Step |
Multiply 8 x 90 and 72 x ? and set them equal to each other |
\$8 × 90\$ = \$72 × ?\$ |
4 |
Step |
Multiply 8 x 90, |
720 = \$72 × ?\$ |
5 |
Step |
To solve for ?, we divide both sides of the equation by 72 |
\$720/72\$ = \$(72 × ?)/72\$ 10 = ? |
6 |
Step |
So, the missing number in the equivalent fraction is \$8/10 = 72/90\$ |

9 |
Choice.A |
This option is incorrect. because, if the missing number is 11, the equivalent fraction is \$8/11\$. However, it does not equal \$72/90\$ after simplification |
\$11\$ |
10 |
Choice.B |
This option is correct. because, simplifying \$8/10\$ and \$72/90\$ both equal \$4/5\$ |
\$10\$ |
11 |
Choice.C |
This option is incorrect. because, if the missing number is 15, then the equivalent fraction is \$8/15\$. However, when we simplify |
\$15\$ |
12 |
Choice.D |
This option is incorrect. because, if the missing number is 12, the equivalent fraction is \$8/12\$. However, it does not simplify to \$72/90\$ |
\$12\$ |
