Question

-5 by 10 plus 9 by 7 + 3 by 20 + - 11 by 14 ssimplify​

Answer 1

Answer:

-5/10 + 9/7 + 3/20 + (-11/14)

=-5/10 + 9/7 + 3/20 - 11/14

=(-5/10 + 3/20) + (9/7 - 11/14)

now we take the LCM of 10 and 20 which is 20  and the LCM of 7 and 14 which is 14

then we multiply both  the numerator and denominator of -5/10 and 9/7 with 2

=(-10+3/20) + (18-11/14)

= -7/20+7/14

here we reduce 7/14 to the lowest terms with which the answer will be 1/2

= -7/20+ 1/2

and then we again take the LCM of both the terms which become 20

then we multiply both the numerator and the denominator with 10 which be

= -7/20 + 10/20

and here, after solving, the final answer will become +3/20

Answer 2

Answer:

-2.57

Step-by-step explanation:

Your Q is

-5/10+9/7+3/20+(-11/14)

Then after trying to solve

= (-5/10+9/7) + {3/20+(-11/14)}

=(-65/70) + (-49/14)

=-130+(-490)/140

=-130-490/140                 ( +*- = -)

=-2.57
