Can you and explain i will give brainliest or

Multiply 3/5 * 12= 3*12/5*1 = 36/5 
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 36/5= 7 1/5 which equals 7.2

Multiply 1/4 * 14 = 1*14/4*1 -14/4 =7/2
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 7/2 = 3 1/2 which equals 3.5

First you need to convert 2 3/20 = 2*10+3/10 =23/10
Then multiply 23/10 * 10 = 23*10/10*1
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 23*10/10*1 = 230/10 which equals 23. 

I hope that this helps! :)
Please mark Brainliest if you believe that I deserve so!

Ok so the answers are going to be in order so 12, 3.5, and 31.5. if u need help, yell at me on my profile.

Well is there a picture
