Question

divide the sum of 12/25 and 21/50 by the product of 1 ⅝ and 9/10 pls tell the answer exams are going on ​

Answer 1

Answer:

72/13

Step-by-step explanation:

12/25+21/50

LCM= 5x5x2 = 50

2x12+1x21 = 24+21 = 45/50 = 9/10(cancel)

now we know the answer of 12/25+21/50 now we have to calculate the product of 1⅝ and 9/10

1⅝ x 9/10 = 13/8x9/10 = 117/80

now let's divide 9/10 and 117/80

9/10÷117/80 = 9/10x80/117 (reciprocal)

9/10x80/117 = 72/13 (cancel)

ans = 72/13

Answer 2

Answer:

72/13

Step-by-step explanation:

12/25+21/50

LCM= 5×5×2=50

2×12+1×21=24+21=45/50 = 9/10
