Answer

Problem

Subtract \$6 25/10 - 4 18/12\$.

Step

Given Fraction

\$6 25/10 - 4 18/12\$

Step

We change the mixed fractions into improper fractions

\$85/10 - 66/12\$

Step

Now, take the LCM of the denominators

LCM of 10,12 is 60

Step

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

\$((85\times6)-(66\times5))/60\$

Step

Subtract the numerators and keep the denominator the same

\$(510 - 330)/60\$

Step

After subtracting we get

\$180/60\$

Step

Divide the numerator with the denominator

\$180\div60\$

Step

After division we get

SumUp

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

Choice.A

This is not the correct answer because the result of the subtraction is 3, not 4

Choice.B

This is not the correct answer because the result of the subtraction is 3, not 1

Choice.C

The correct option is 3rd because after simplifying the given expression, the result is 3

Choice.D

This is not the correct answer because the result of the subtraction is 3, not 6
