The operation symbol and the exponent are missing in the equation shown below. 7,320
10
0.07320
Which operation symbol and exponent should go in the boxes to make the
equation true?

The operating symbol is divide (/) and the exponent is 5

Step-by-step explanation:

Given

Required

Fill in the gap

Multiply the right hand side by 1

Express 1 as 100000/100000 because 100000/100000 = 1

Split the fraction

Multiply 0.7320 and 10000

Express as an exponent

Change the * sign to /

Compare the expression on the right hand side with the left hand side base on the order of appearance;

Hence, the operating symbol is / and the exponent is 5

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
