38
40

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: 40

$First comma space we space need space to space find space the space compatible space numbers space for space both. Hence comma 1560 space is space close space to space its space hundreds space place. space So comma space 1560 space rounds space to space 1600. 42 space is space close space to space its space tens space place. space So comma space 42 space rounds space to space 40. space space therefore 1600 space and space 40 space are space compatible space numbers. Now comma space Using space division space patterns comma 1600 divided by 40 space equals space 160 divided by 4 space equals space 40 therefore space 1600 divided by 40 space equals space 40 Here comma 40 space cross times 40 space equals space 1600 So comma space straight a space good space estimate space of space 1560 divided by 42 space is space 40. space$
