1 answer

To calculate 712156, we first convert both mixed numbers into improper fractions.

  1. Convert 712: 712=(7×2)+12=14+12=152

  2. Convert 156: 156=(1×6)+56=6+56=116

Now we can subtract the two improper fractions: 152116

To subtract these fractions, we need a common denominator. The least common multiple of 2 and 6 is 6.

  1. Convert 152 to a fraction with a denominator of 6: 152=15×32×3=456

Now we can perform the subtraction: 456116=45116=346

  1. Simplify 346: 346=173

Next, we convert 173 back into a mixed number.

  1. Divide 17 by 3:
    • 3 goes into 17 five times (5 x 3 = 15)
    • Remainder is 2.

So, 173=523.

Thus, 712156=523.

The answer in the required format is: 523
