Answer:
1241
Step-by-step explanation:
∴
L.C.M. of 28, 36 and 45 = 2 × 2 × 3 × 3 × 5 × 7 = 1260
∴
the required number is 1260 - 19 = 1241
Hence, if we add 19 to 1241 we will get 1260 which is exactly divisible by 28, 36 and 45.
Answer: 300
Step-by-step explanation: 300+200=500
then 500-200=300
1 : 500,000
multiplied by 7 cm is
7 cm : 3,500,000 cm

= 7 cm : 35 km . . . (1000 m in 1 km)
The actual distance between the towns is 35 km.
