6. Every floor of a 20 storey building is 4 m high. A lift moves 2 m per second. How long will it take 1
from 4th floor to 14th floor?
7. The temperature of a city was 28°C on Tuesday. The temperature rose by 1.5°C on everyday upto Fri
fell by 2.5°C on Saturday. What was the temperature of the city on Saturday?
1.
DIVISION OF INTEGERS
Division is the inverse operation of multiplication
Since
7 x 8 = 56.
7 is contain into 56 eight times.
Thus
56 + 7 = 8
Similarly,
6 * 5 = 30,
