Question

Q. 1. Using appropriate properties find:
-2/3×3/5+5/2-3/5×1/6​

Answer 1

Answer:

$\frac{ - 2}{3} \times \frac{3}{5} + \frac{5}{2} - \frac{3}{5} \times \frac{1}{6} \\ \\ = \frac{ - 2 \times 3}{3 \times 5} + \frac{5}{2} - \frac{3 \times 1}{5 \times 6} \\ \\ = \frac{ - 6}{15} + \frac{5}{2} - \frac{3}{30} \\ \\ = (\frac{ - 6 \times 2}{15 \times 2} + \frac{5 \times 15}{2 \times 15} )- \frac{3}{30} \\ \\ = \frac{ - 12 + 75}{30} - \frac{3}{30} \\ \\ = \frac{63}{30} - \frac{3}{30} \\ \\ = \frac{60}{30} \\ \\ = 2$

USE BODMAS RULE!!!

Answer 2

Answer:

answer =2

Step-by-step explanation:

= -2÷3 × 3÷5 + 5÷2 -3÷5 × 1÷6

= -2÷1 × 1÷5 + 5÷2 -1÷5 ×1÷2

= -2÷5 + 5÷2 -1÷10

= -4+25÷10 -1÷10

= 21÷10 - 1÷10

= 20÷10

= 2÷1

= 2
