Question

simplify 4 upon 10 +-13 upon 15 +-90 upon 50​

Answer 1

Step-by-step explanation:

4/10 + (-13/15) + (-90/50)

= 4/10 - 13/15 - 90/50

=4×15/10×15 - 13×10/15×10 - 90×3/50×3

=60/150 - 130/150 - 270/150

=60-130-270/150

=340/150

(zero and zero gets cancle)

Therefore 34/15 is your answer

and cannot be further simplify
