Problem |
Solving the Proportion \$6 : x\$ = \$32 : 15\$. |
|
2 |
Step |
Given Proportion |
\$6 : x\$ = \$32 : 15\$ |
3 |
Step |
First, convert the provided proportion into a fraction |
\$6/x\$ = \$32/15\$ |
4 |
Step |
To solve the proportion, begin by cross-multiplying |
\$(15 \times 6)\$ = \$(32 \times x)\$ ⇒ \$90 = 32x\$ |
5 |
Step |
Divide both sides by the number connected to the variable |
\$90/32 = (32x)/32\$ |
6 |
Step |
The value of x is: |
\$x\$ = \$90/32\$ = \$2.8125 \$ |
