Question

The estimated value of 512÷ 54 is ___________.

50
11
10
60

hint Hint:

When you divide multiples of 10, 100, and 1,000 knowing your basic facts and place-value, patterns can help you find the answer.

The correct answer is: 10

$First comma space we space need space to space find space the space compatible space numbers space for space both. Hence comma 512 space is space close space to space its space hundreds space place. space So comma space 512 space rounds space to space 500. 54 space is space close space to space its space tens space place. space So comma space 54 space rounds space to space 50. space space therefore 500 space and space 50 space are space compatible space numbers. Now comma space Using space division space patterns comma 500 divided by 50 space equals space 50 divided by 5 space equals space 10 therefore space 500 divided by 50 space equals space 10 Here comma 10 space cross times space 50 space equals space 500 So comma space straight a space good space estimate space of space 500 divided by 50 space is space 10. space$

There are 5000 oranges with a farmer. If he can pack 50 oranges in a box. The number of boxes does he needs in total is ________.

STEP BY STEP SOLUTION

50 oranges = 1 box
1 orange =1/50 box
so, to pack 5000 oranges
total box= 5000 $cross times$ 1/50
total box= 5000/50
total box = 100
So, the farmer will need 100 boxes to pack 5000 oranges
