Mua 1 hộp kẹo hết số tiền là:
80000:4=20000 ( đồng )
Mua 5 hộp kẹo hết số tiền là:
20000x5=100000 ( đồng )
Đáp số: 100000 đồng
a) 125 : x = 5 b) x : 9 = 65 c) 342 : x = 6
x = 125:5 x = 65 x 9 x= 342 : 6
x = 25 x = 585 x= 57
d) 128 - x = 85 e) x - 356=74 g) 128 + x = 426
x = 128-85 x = 74+356 x= 426 - 128
x = 43 x = 430 x= 298
