Explicație pas cu pas:

Salut!

$(a)\:\: \bf 810:b = 9\:\:\Big|\cdot b \implies810=9b\:\:\Big|:9\implies \boxed{\bf b = 90}$

$(b)\:\: \bf b:2 = 113\:\:\Big|\cdot 2 \implies \boxed{\bf b = 226}$

$(c)\:\: \bf b:1 = b \implies \boxed{\bf b =b}$

$(d)\:\: \bf 2400:b = 120\:\:\Big|\cdot b \implies 2400=120b\:\:\Big|:120\implies \boxed{\bf b = 20}$

$(e)\:\: \bf 36406:158 = b \implies b=\!{^{^{^{^{^{^{\displaystyle 2)}}}}}}}\!\!\!\!\dfrac{36406}{158} \implies \boxed{\bf b =\dfrac{18203}{79}}$

$(f)\:\: \bf b:37 = 573\:\:\Big|\cdot 37 \implies \boxed{\bf b = 21201}$
