অনুশীলনী 1.2 – Exercise 1.2 (Bilingual)
Question 1 / প্ৰশ্ন 1
Find:
উলিয়াওক:
(i) -5/7 + 3/7
= (-5 + 3)/7 = -2/7
(ii) 2/3 + (-4/3)
= (2 − 4)/3 = -2/3
(iii) 5/6 + (-1/6)
= 4/6 = 2/3
Question 2 / প্ৰশ্ন 2
Subtract:
বিয়োগ কৰক:
(i) 7/10 − 3/10
= (7 − 3)/10 = 4/10 = 2/5
(ii) 5/9 − (-4/9)
= (5 + 4)/9 = 9/9 = 1
(iii) -3/5 − 2/5
= (-3 − 2)/5 = -5/5 = -1
Question 3 / প্ৰশ্ন 3
Multiply:
গুণ কৰক:
(i) 3/4 × 2/5
= 6/20 = 3/10
(ii) -5/6 × 3/7
= -15/42 = -5/14
(iii) -2/3 × -4/5
= 8/15
Question 4 / প্ৰশ্ন 4
Divide:
ভাগ কৰক:
(i) 4/5 ÷ 2/3
= 4/5 × 3/2 = 12/10 = 6/5
(ii) -7/9 ÷ 14/3
= -7/9 × 3/14 = -1/6
(iii) 5/8 ÷ (-10/3)
= 5/8 × 3/(-10) = -3/16
