Question

c) 28.192 + 72.192 + 2022 .

d) 6 : {400 : (500 - (125 + 25.7) }

Answer 1

a) \(28.192+72.192+2022\)

\(=192.\left(28+72\right)+2022\)

\(=192.100+2022\)

\(=19200+2022\)

\(=21222\)

_________

d) \(6:\left\{400:\left[500-\left(125+25.7\right)\right]\right\}\)

\(=6:\left\{400:\left[500-300\right]\right\}\)

\(=6:\left\{400:200\right\}\)

\(=6:2\)

\(=3\)

Answer 2

\(c,28\cdot192+72\cdot192+2022\)

\(=192\cdot\left(28+72\right)+2022\)

\(=192\cdot100+2022\)

\(=19200+2022\)

\(=21222\)

\(d,6:\left\{400:\left[500-\left(125+25\cdot7\right)\right]\right\}\)

\(=6:\left\{400:\left[500-\left(125+175\right)\right]\right\}\)

\(=6:\left[400:\left(500-300\right)\right]\)

\(=6:\left(400:200\right)\)

\(=6:2\)

\(=3\)
