a) \(86\times15+150\times1,4\)
\(=86\times15+15\times10\times1,4\)
\(=86\times15+15\times14\)
\(=15\times\left(86+14\right)\)
\(=15\times100\)
\(=1500\)
A)86.15+150.1,4
= 86.15 + 15.10.1,4
= 15(86 + 14)
= 15.100
= 1500
B)93.32+14.16
= 93.16.2 + 14.16
= 16(186 + 14)
= 16.200
= 3200
a,86.15+150.1,4=(86.15)+(150.1,4)=1290+210=1500
b,93.32+14.16=(93.32)+(14.16)=2976+224=3200
c,98,6.199-990.9,86=(98,6.199)-(990.9,86)=19621,4-9761,4=9860
\(a,86\cdot15+150\cdot1,4\)
\(=86\cdot15+15\cdot14\)
\(=15\cdot\left(86+14\right)\)
\(=15\cdot100\)
\(=1500\)
b) \(93\times32+14\times16\)
\(=93\times16\times2+14\times16\)
\(=16\times\left(93\times2+14\right)\)
\(=16\times200\)
\(=3200\)
