Answer:
I. 1/5
II. -1/14
III. 2/9
Step-by-step explanation:
(i) (-3/5) + (-2/7)
Opening up the bracket;
3/5 - 2/5 =
Lowest common multiple (LCM) = 5
(3 - 2)/5
= 1/5
(ii) (-2/7) - (-3/14)
Opening up the bracket;
-2/7 + 3/14 =
Lowest common multiple (LCM) = 14
(-4 + 3)/14 = -1/14
(iii) (-4/ 9) = (- 2/3)
Rearranging the fraction, we have;
-4/9 + 2/3 =
Lowest common multiple (LCM) = 9
(-4 + 6)/9 = 2/9
Answer:
1. 7
2. 1.25, 5/4, 1 1/4
3. -0.7
4. 20
5. 4.8
6. 30
7. 1.4
8. 28
9. -3.3 (the last 3 is infinite)
Answer:
<h3>(3y2+5y-7)+2(y3-4y2+5)</h3>
3y2+5y-7+2y3-8y2+10
3y2-8y2+5y-7+10
-5y2+5y+17
Answer:
Question 1 is, the blue figure is larger than the red figure
Question 2 is, the red and the blue figure are equal
