My wife however did bake cookies this year 40% of the cookies she baked chocolate chip if she baked 36 chocolate chip cookies how many total cookies does she bake

The total number of cookies is 90

Step-by-step explanation:

As, they said 40% of the total number of cookies is 36, we will take the total as "x"

= 40% of x = 36

40/100 X x = 36

40x = 36 x 100

40x = 3600

x = 3600/40

x = 90

So total cookies she baked = 90

Let's check!

So 40% of 90 need to be 36

So,

40/100 x 90 = 3600/100

= 36

So therefore, total number of cookies = 90

so, converting firstly the mixed fractions to improper fractions and then "adding".
