प्रश्न
Different mathematical operations are given in the two rows below. Find out the number you get in each operation and make equations.
16 ÷ 2; 5 × 2; 9 + 4; 72 ÷ 3; 4 + 5; 8 × 3; 19 - 10; 10 - 2; 37 - 27; 6 + 7
उत्तर
16 ÷ 2 = 8
5 × 2 = 10
9 + 4 = 13
72 ÷ 3 = 24
4 + 5 = 9
8 × 3 = 24
19 − 10 = 9
10 − 2 = 8
37 − 27 = 10
6 + 7 = 13
So,
16 ÷ 2 = 10 − 2
5 × 2 = 37 − 27
9 + 4 = 6 + 7
72 ÷ 3 = 8 × 3
4 + 5 = 19 − 10
