a: =16x200=3200
b: \(=3.527\cdot100=352.7\)
c: =1/9(5/8+3/8)=1/9
\(=16\times\left(124+76\right)=16\times200=3200\)
\(=3,527\times\left(96,28+3,72\right)=3,527\times100=352,7\)
\(=\left(\dfrac{5}{8}+\dfrac{3}{8}\right)\times\dfrac{1}{9}=\dfrac{1}{9}\)
\(124x16+16x76=16x\left(124+76\right)=16x200=3200\\ 96,28x3,527+3,527x3,72=3,527x\left(96,28+3,72\right)=3,527x100=352,7\\ \dfrac{5}{8}x\dfrac{1}{9}+\dfrac{3}{8}x\dfrac{1}{9}=\dfrac{1}{9}x\left(\dfrac{5}{8}+\dfrac{3}{8}\right)=\dfrac{1}{9}x\dfrac{8}{8}=\dfrac{1}{9}x1=\dfrac{1}{9}\)
`124 xx 16 + 16 xx 76 = 16 xx (124 + 76) = 16 xx 200 = 3200`
`96,28 xx 3,527 + 3,527 xx 3,72 = 3,527 xx ( 96,28 + 3,72) = 3,527 xx 100=352,7`
`5/8 xx 1/9 + 3/8 xx 1/9 = (5/8 + 3/8) xx 1/9 = 1 xx 1/9 = 1/9`
1) 124 x 16 + 16 x 76
= 16 x ( 124 + 76 )
= 16 x 200
= 3200
2)96,28 x 3,527 + 3,527 x 3,72
= 3,527 x ( 96,28 + 3,72 )
= 3,527 x 100
=352,7
3) 5/8 x 1/9 + 3/8 x1/9
= 1/9 x ( 5/8 +3/8)
=1/9 x 1
= 1/9
