Explanation

Answer

Problem

Caluculate \$31/3 − 1/4\$.

Step

Give fractions are

\$31/3\$, \$1/4\$

Step

Least Common Multiple (LCM) between the denominators

LCM of 3, 4 = 12

Step

Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator

\$((31 × 4) - (1 × 3)) /12\$

Step

Subtract the numerators and keep the denominator the same

\$(124 - 4)/12\$ = \$120/12\$

Step

After subtracting, the resulting fraction is \$120/12\$

Step

Simplify the fraction the we get result as 10

Answer

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

This option is incorrect because the difference between \$31/3\$ and \$1/4\$ is not equal to 16

Choice.B

This option is incorrect because it does not match the accurate result of \$31/3\$−\$1/4\$

Choice.C

This option is incorrect because 11 is not the difference between \$31/3\$ and \$1/4\$

Choice.D

This option is correct because the difference between \$31/3\$ - \$1/4\$ is 10

Sumup

Can you summarize what you’ve understood in the above steps?
