What is the product of 5 7/10 - 5/18

244/45

Step-by-step explanation:

Simplify the following:

5 + 7/10 - 5/18

Put 5 + 7/10 - 5/18 over the common denominator 90. 5 + 7/10 - 5/18 = (90×5)/90 + (9×7)/90 + (5 (-5))/90:

(90×5)/90 + (9×7)/90 + (5 (-5))/90

90×5 = 450:

450/90 + (9×7)/90 + (5 (-5))/90

9×7 = 63:

450/90 + 63/90 + (5 (-5))/90

5 (-5) = -25:

450/90 + 63/90 + (-25)/90

450/90 + 63/90 - 25/90 = (450 + 63 - 25)/90:

(450 + 63 - 25)/90

488/90

The gcd of 488 and 90 is 2, so 488/90 = (2×244)/(2×45) = 2/2×244/45 = 244/45:

 244/45
