Question

Решите 1) 76м39см–41м24см,. 2)22км527м–17км783м,. 3)5мин17сек–15мин35сек

Answer 1

1) 76м 39см - 41м 24см = 35м 15см.
2) 22км 527м - 17км 783м = 21км 744м.
3) 15мин 35сек - 5мин 17сек = 10мин 18сек.

Answer 2

1. To subtract 76m 39cm from 41m 24cm, we'll align the units and subtract each part separately:

76m 39cm

• 41m 24cm

First, subtract the centimeters:

39cm - 24cm = 15cm

Then subtract the meters:

76m - 41m = 35m

So the result is 35m 15cm.

2. To subtract 22km 527m from 17km 783m, we'll follow the same process:

22km 527m

• 17km 783m

First, subtract the meters:

527m - 783m = -256m

Since the result is negative, we need to borrow 1 from the kilometers:

(17km - 1km) = 16km

Now let's subtract the kilometers:

16km - 1km = 15km

So the result is 15km -256m.

3. To subtract 5min 17sec from 15min 35sec, we'll align the units and subtract each part separately:

15min 35sec

• 5min 17sec

First, subtract the seconds:

35sec - 17sec = 18sec

Then subtract the minutes:

15min - 5min = 10min

So the result is 10min 18sec.
