Answer :
you can go about it in two different ways.
9 3/10 + 7 2/10 * 1/5 = 2/10 *
= 16 5/10
= 16 1/2
or
93/10 + 37/5
93/10 + 72/10
= 165/10
=16 5/10
= 16 1/2
9 3/10 + 7 2/10 * 1/5 = 2/10 *
= 16 5/10
= 16 1/2
or
93/10 + 37/5
93/10 + 72/10
= 165/10
=16 5/10
= 16 1/2
9 and 3/10 needs to be made into an improper fraction.
9x10=90+3=93.
93/10
7 and 1/5 needs to be made into an improper fraction, also.
7x5=35+1=36
36/5
Now, you need to make both numbers have common denominators.
93 x 2 186
10 x 2 20
36 x 4 144
5 x4 20
Now, you add them!!
Don't forget to keep the denominators the same!
186 + 144 330
20 20 20
Now, reduce!
330
20
330 goes into 20, 16 times unevenly. 16x2=320, so you have 10 left over.
16 and 10/20.
Now, reduce!
10/20=1/2
Now, your answer is 16 and 1/2!!!
I hope this helped you!!
