Question

quanto é 4+6 = x 100= : 5= x 578 =

Answer 1

$4+6 = x 100\\\\x\cdot \:100=4+6\\\\x\cdot \:100=10\\\\\frac{x\cdot \:100}{100}=\frac{10}{100}\\\\x=\frac{1}{10}\\\\\\\\5= x 578 \\\\x\cdot \:578=5\\\\\frac{x\cdot \:578}{578}=\frac{5}{578}\\\\=\frac{5}{578}$

$4+6= *1000 : 5 = *578\\\\10= *1000 : 5 = *578\\\\10000: 5 = *578\\\\2000 *578\\\\1156000$
