To which number should 2/3 be added to give -11/14
Answers
Answer:
8) Simplify: 1)-2 + (3/8) + (-1/5).2) (2/3) + (-7/11) + (-1/4)
9) Verify that a + b = b + a by taking (1) a = -7/5, b = 217
(2) a = -1, b = -2/3
10) Verify that (a+b)+c. =a+(b+c) by taking
(1) a = -2.b = -2/3, c = -3/4
(2) a = -12. b = -9/11, c = 71-12
11) Simplify the following:
1) (2/3) + (-4/5) + 1 + (-2/3) + (-11/5)
2)(5/8) + (-8/9) + 0 + (-13/3) + (17/24)
12) Subtract : 1) (-3/4) from (1/2) 2) (5/8) from (-3/14)
13) What should be added to (-7/20) to get (-2/5)?
14) The sum of two rational numbers is (-3/7). If one of the number is (-5/8) find the other.
15) The sum of two rational numbers is (-5/8). If one of the number is (-6/11), find the other number.
16) To which number should (2/3) be added to give (-11/4)?
17) From which number should (11/4) be subtracted to give (-11/4)?
Answer:
x=-41/12
Step-by-step explanation:
2/3+x=-11/4
x=-11/4-2/3
x=-33-8/12
x=-41/12
