Answer:
\(653\)
Step-by-step explanation:
we know that
the difference between \(900\) and \(247\) is equal to subtract \(247\) from \(900\)
so
\(900-247\)
remember that
\(247=200+40+5+2\)
substitute in the expression above
\(900-247=900-(200+40+5+2)\)
\(=900-200-40-5-2\) ------> \(=(900-200)-40-5-2\)
\(=700-40-5-2\) -----> \(=(700-40)-5-2\)
\(=660-5-2\) -----> \(=(660-5)-2\)
\(=655-2\)
\(=653\)
