Solution
The correct option is D 3
Number of millimetres in 1 cm = 10.
Length of a big frog = 30.5 cm
Length of a big frog in mm = 30.5 × 10
= 305 mm
Total length of 3 big frogs = 305 × 3
= 915 mm
Total length of 4 big frogs = 305 × 4
= 1220 mm
We know that 1 m = 1000 mm.
So, we can say that only three frogs can fit on the 1 m scale.
