Question

1дм8см-5см=?;14см:2=?

Answer 1

Ответ:

1 дм8 см-5см=1 дм 3см=13см

14см:2=7см

Answer 2

To solve the expressions, we'll perform the following calculations:

1. Subtracting 5 cm from 1 dm 8 cm: 1 dm 8 cm = 18 cm (since 1 dm = 10 cm) 18 cm - 5 cm = 13 cm

So, 1 dm 8 cm - 5 cm = 13 cm.

2. Dividing 14 cm by 2: 14 cm ÷ 2 = 7 cm

So, 14 cm divided by 2 is equal to 7 cm.
