How do you solve 800m 35cm-154m 49cm for the smaller unit?

bearhunter [10]

1 m = 100 cm
800 m = 800 x 100 = 80000 cm
Therefore, 800 m 35 cm = 80000 cm + 35 cm = 80035 cm

Also, 154 m = 154 x 100 = 15400 cm
Therefore, 154 m 49 cm = 15449 cm

Therefore, <span>800m 35cm - 154m 49cm = 80035 cm - 15449 cm = 64586 cm = 645m 86cm</span>

Answer:

finding the number of equal-sized parts into which a number can be split

Step-by-step explanation:

Let us split the number 80 into 10 equal parts.

80 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8

= 8 + 8 + 8 +...to 10 times

= 8(10)

or $\frac{80}{10} =8$

So, if N is any number and p is one of its equal part, then the number of parts into which N is split by p is $\frac{N}{p}$ .

Hence, finding the number of equal-sized parts is best modeled with a division expression.
