Question

13)37,42:4,6-(1,43+2,728)х1,5
14)7,2х3,8+(3,24-2,1312):0,42
15)3,564:0,66+0,4992:0,052-83х0,107

Answer 1

13)37,42:4,6-(1,43+2,728)*1,5=1,898
1)1,43+2,728=4,158
2)37,42:4,6=8,135
3)4,158*1,5=6,237
4)8,135-6,237=1,898
14)7,2*3,8+(3,24-2,1312):0,42=30
1)3,24-2,1312=1,1088
2)7,2*3,8=27,36
3)1,1088:0,42=2,64
4)27,36+2,64=30
15)3,564:0,66+0,4992:0,052-83*0,107=6,119
1)3,564:0,66=5,4
2)0,4992:0,052=9,6
3)83*0,107=8,881
4)5,4+9,6=15
5)15-8,881=6,119
