Проверка 8+12+36=56
ответ
2:3:9=8:12:36
в)
Сложим части
3/4+1,5+4=3/4+1 1/2+4=3/4+1 2/4+4=
5 5/4=6 1/4=25/4
Чему равна 1 часть?
12,5=12 5/10=12 1/2=25/2
25/2:25/4=2
Первое число 2•3/4=3/2=1 1/2
Второе число. 2•3/2=3
Третье число 2•4 =8
Проверка
1 1/2+3+8=12 1/2=12,5
ответ
3/4:1,5:4= 1/2:3:8
г) 4+11=15
240:15=16
Первое число

Второе число
16•11=176
Проверка
176+64=240
4:11=64:176
а)
сложим части
4/5+1 1/3=12/15+1 5/15=1 17/15=2 2/15=
32/15
7,2=7 2/10=7 1/5=36/5
Чему равна 1 часть?

Первое число
27/8•4/5=2 7/10
Второе число
27/8•4/3=9/2=4 1/2
Проверка
2 7/10+4 1/2=2 7/20+4 5/10=6 12/10=7 2/10=7,2
ответ
0,8:1 1/3=2 7/10:4 1/2
Пошаговое объяснение:
В - цифра единиц
Само число равно 10•А + В
Получается система уравнений:
А+2=В
А^2 + В^2=34
Подставляем во второе уравнение В
А^2 + (А+2)^2 =34
А^2 + А^2 + 4А + 4 -34=0
2А^ + 4А - 30 =0
А^2 + 2А - 15 =0
А1=3
А2=-5 не подходит
В=2+А=2+3=5
Это число 53
