Question

17 4/11*7/10-7/10*7 4/11

Answer 1

17 4/11*7/10-7/10*7 4/11 = 1337/110-567/110=7

Answer 2

To evaluate the expression 17 4/11 * 7/10 - 7/10 * 7 4/11, we need to follow the order of operations (PEMDAS/BODMAS) to perform the calculations. Here's the step-by-step solution:

Step 1: Convert mixed numbers to improper fractions. 17 4/11 = (11 * 17 + 4)/11 = 191/11 7 4/11 = (11 * 7 + 4)/11 = 81/11

Step 2: Multiply the fractions. (191/11) * (7/10) = (191 * 7)/(11 * 10) = 1337/110

Step 3: Multiply the remaining fractions. (7/10) * (81/11) = (7 * 81)/(10 * 11) = 567/110

Step 4: Subtract the second product from the first product. 1337/110 - 567/110 = (1337 - 567)/110 = 770/110 = 7

Therefore, the value of the expression 17 4/11 * 7/10 - 7/10 * 7 4/11 is equal to 7.
