1.What does 0.9 cm mean? It is the same as——— millimetres. We can also say this is nine-tenths of a cm. Right?
Ans. 0. 9 cm = 9 mm
Yes, it is nine-tenth of a cm.
2.So 30.5 cm is the same as———-cm and———– millimetres.
Ans. 30.5 cm = 30 cm and 5 millimeter.
3.About how many of the big frogs will fit on the 1 m scale?
Ans. 1 m = 100 cm
If 100 is divided by 30 then we get 3 as quotient and 10 as remainder.
ncert-solutions-class-5-maths-chapter-10-tenths-hundredths-3
So, it can be said that 3 to 4 such frogs can sit on a 1m scale.
4.If they sit in a straight line about how many of the small frogs will cover 1 m?
Ans. 1 m = 100 cm = 1000 mm
If 1000 is divided by 9 mm then we get 111 as quotient and 1 as remainder. So, it can be said that 111 small frogs will cover 1 m.
