Question

simplify the following
1) 500×2000÷200+1000-5000
2)27÷9×15-3+12
3)12+70÷7×1-20

​

Answer 1

Step-by-step explanation:

1. 500 × 2000 ÷ 200 + 1000 - 500

Using BODMAS rule

= 500 × 10 + 1000 - 500

= 5000 + 1000 - 500

= 6000 - 500

= 5500

2. 27 ÷ 9 × 15 - 3 + 12

Using BODMAS rule

= 3 × 15 - 3 + 12

= 45 - 3 + 12

= 45 + 9

= 54

3. 12 + 70 ÷ 7 × 1 - 20

USING BODMAS RULE

= 12 + 10 × 1 - 20

= 32 - 20

= 12

✌️I hope it helps you

Answer 2

Answer:

1)1000

2)54

3)2

Step-by-step explanation:

500×2000÷200+1000-5000=1000

500×2000 =10,00,000 ÷200 =5000+1000= 6000-5000=1000

27÷9×15-3+12=54

27÷9=3×15=45-3=42+12=54

12+70÷7×1-20=2
