Let's rewrite each fraction as an equivalent fraction with
100 in each denominator.
47/50
Multiply numerator and denominator by 2 to get
94/100
33/49
49 x 2 = 98
So, to get 100 in the denominator, we must multiply 49
by a number a little bit bigger than 2
Multiply numerator and denominator
by a number a little bit bigger than 2 to get (a number a little bigger than 66)/100
Let's rewrite "a number a little bigger than 66" as "66+"
So, we get:
(66+)/100
Now add the equivalent fractions
94/100 +
(66+)/100 = (160+)/100
= 1.6+ (a number a little bit bigger than 1.6
