Round 241639
To merest thousand

242000

Step-by-step explanation:

The thousands place has a one. The number after the one is the rounding number.

6 is the rounding number.

6 is greater than 5, so we round up.

241639 ≈ 242000

242,000

Looking at the thousand place we underline the 1.

Next step we put a right arrow pointing to 6 in the hundreds place.

6 > 5

Add 1 in the thousand place and it'll round up to 2.

241,639 to the nearest thousand is 242,000  

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
