Question

Answer 1

a/\(24,3+y:16-3,4=30,34\)
\(24,3+y:16=30,34+3,4\)
\(24,3+y:16=33,74\)
\(y:16=33,74-24,3\)
\(y:16=9,44\)
\(y=9,44\times16\)
\(y=151,04\)
b/\(\dfrac{3}{4}\times y:\dfrac{1}{2}=\dfrac{4}{5}\)
\(\dfrac{3}{4}\times y=\dfrac{4}{5}\times\dfrac{1}{2}\)
\(\dfrac{3}{4}\times y=\dfrac{2}{5}\)
\(y=\dfrac{2}{5}:\dfrac{3}{4}\)
\(y=\dfrac{8}{15}\)
c/\(9,15\times y+2,85=47,685\)
\(9,15\times y=47,685-2,85\)
\(9,15\times y=44,835\)
\(y=44,835:9,15\)
\(y=4,9\)
d/\(y\times4,5:7,2=13,4-12,5\)
\(y\times4,5:7,2=0,9\)
\(y\times4,5=0,9\times7,2\)
\(y\times4,5=6,48\)
\(y=6,48:4,5\)
\(y=1,44\)
