Question

3 5/12 - 1 3/6=
(35/39:7/13):(49/36):(7/4)=
( 2 2/3+ 1 5/6):(1 1/2)=

Va rog mult dau coroana!

Answer 1

Salut!

a) 3 x 12 + 5/12 - 1 x 6 + 3 = 41/12 - 9/6 = 41/12 - 9/6 | x 2 = 41/12 - 18/12 = 29/12

b) (35/39 x 13/7) : 49/36 x 4/7 = 5/3 :7/9 = 5/3 x 9/7 = 5/1 x 3/1 = 15/1 = 15

c) (8/3 + 11/6) : (3/2) =

• 8/3 | x 2

= (16/6 + 11/6) : (3/2) = 27/6 x 2/3 = 9/3 = 3/1 = 3

o seara/zi frumoasa!

Answer 2

1. $\frac{3}{4}$ = 0.75

2. ($\frac{35}{39}$ x $\frac{13}{7}$) x $\frac{36}{49}$ x $\frac{4}{7}$

$\frac{5}{3}$ x $\frac{36}{49}$ x $\frac{4}{7}$

5 x $\frac{12}{49}$ x $\frac{4}{7}$

$\frac{240}{343}$
