Question

9/20 x 2/3 + 5 / 14 х 7/25

Answer 1

9/20×2/3+5/14×7/25=2/5

Answer 2

9/20 x 2/3+5/14 x 7/25=9̶/20 х 2/3̶+ 5/14 х 7/25= 3/20 х 2+ 5/14 х 7/25=3/10+1/2 х 1/5= 3/10+1/10= 4/10 =2/5 (альтернативный вид =0,4)

Answer 3

To solve the expression, let's perform the operations step by step:

Step 1: Evaluate 9/20 x 2/3 To multiply fractions, simply multiply the numerators together and multiply the denominators together: (9/20) x (2/3) = (9 x 2) / (20 x 3) = 18 / 60

Step 2: Evaluate 5/14 x 7/25 Similarly, multiply the numerators and denominators together: (5/14) x (7/25) = (5 x 7) / (14 x 25) = 35 / 350

Step 3: Simplify the fractions, if possible. Both fractions can be simplified. First, simplify 18/60: 18/60 = (6 x 3) / (6 x 10) = 3/10

Similarly, simplify 35/350: 35/350 = (5 x 7) / (50 x 7) = 1/10

Step 4: Add the simplified fractions. 3/10 + 1/10 = (3 + 1) / 10 = 4/10

Step 5: Further simplify, if possible. 4/10 can be reduced to its simplest form: 4/10 = (2 x 2) / (2 x 5) = 2/5

So, the final result is 2/5.
