estimate: 4 1/3 x 2 4/5. estimate: 5 9/10 x 2 2/3. multiply: 1/4 x 1/2. multiply: 3/4 x 8/9. multipl: 15 x 2/3

Question

these are differnce questions please help me and tell me the answer! thank u

Answer 1

dude.. these are very simple... what we are dealing with are mixed fractions ... like two and a half... will mean two plus a half and will be written as 2 1/2 ... to convert this into a simple fraction.. u need to write that as 2 + 1/2 and after taking the LCM we get it as 5/2....
thats an example so that u dont have any problems with conversions

now to the problems..

1. 4 1/3= 4+1/3=13/3
2 4/5=2+4/5=14/5
therefore 4 1/3*2 4/5= 13/3*14/5 ... =(13*14)/(3*5)
take the next ones...u will be able to do them

just remember... convert all mixed fractions into simple fractions and then when u want to multiply them the multiply the numerators and divide the product with the multiplication of the denominators

Answer 2

estimate 4x3=12
estimate 6x3=18
multiply 1/2 x 1/4=1/ 8
multiply 3/4 x 8/9= 24/36=2/3
multiply 15 x 2/3=30/3=10
