АВ=0,6м
АD=9/20м
Приведем к общему знаменателю:
0,6м=6/10м=12/20м
12/20м > 9/20м
Значит, большая сторона будет АВ и DC по 0,6м . Меньшая сторона будет AD и BC по 9/20 м . См вложение:
2)
MN=2/3дм=4/6 дм
MK=5/6 дм
NK=1/2дм=3/6дм
см вложение.
сумма длин катетов равна:
2/3дм + 1/2дм = 7/6 дм = 1 1/6 дм
3)
молоко 3/4 объема
сок 5/6 объема
морс 2/3 объема.
Приведем к общему знаменателю:
3/4=9/12
5/6=10/12
2/3=8/12
Меньший сосуд - это морс
Средний сосуд - это молоко
