Convert the mixed number 1 2/3 to an improper fraction.

Mathematics
1 answer:
rodikova [14]3 years ago
6 0

Answer:

5/3

Step-by-step explanation:

An improper fraction is a fraction, not in mixed form, where the numerator (top half) is greater than the denominator (bottom half). Since this fraction is 1 2/3, we already have 1 full and 2/3 full. So, since the 1 is full, it means that in fraction form it equals 3/3.

We can finally add the fractions. 2/3+3/3=5/3.

A total of 765 tickets were sold for the school play. They were either adults or students tickets. There were 65 more student ti
Brrunno [24]

Answer: 350 adult tickets

Step-by-step explanation:

(omg I remember this question!)

  • a stands for the number of adult tickets sold

student tickets : a + 65

<em>the equation for the prob: </em>

765 = a + (a + 65)

<em>solve:</em>

combine 'like terms'

1.) 765 = a + a + 65

2.) 765 = 2a + 65

<u>- 65         - 65 </u>

700= 2a

divide by 2

700/2 = 2a/2

<em>(700/2 = 350) </em>

<em>(the "2" in 2a is cancelled out by the other 2)</em>

<u>350 = a </u>

The sum of the digits of a two-digit number is 9. If the digits are reversed,the new number is 9 more than the original number.F
hodyreva [135]

Answer:

45

Step-by-step explanation:

Let the original number be xy where y is unit and x is tens hence original number is 10x+y When reversed, the new number is yz hence 10y+x

We know that the original number plus 9 is the reversed number hence

10x+y+9=10y+x

9y-9x=9 which when simplified we obtain that

y-x=1 equation 1

Originally, we are told that the sum of x and y is 9 hence

y+x=9 equation 2

Solving equation 1, it means y=x+1

Substituting the above into equation 2

x+1+x=9

2x=9-1

2x=8

x=8/2=4

Since y=x+1 then y=4+1=5

Therefore, the original number, xy is 45

An epidemiologist is observing the decay pattern of a pathogenic bacteria after applying a vaccine. He starts with 2,000 bacteri
Viktor [21]

Answer:

Number of bacteria after 36 hour (A) = 381 (Approx)

Step-by-step explanation:

Given:

Number of bacteria (p) = 2,000

Total time (n) = 36 hours

Decay rate = 4.5 % = 0.045 per hour

Find:

Number of bacteria after 36 hour (A)

Computation:

A=p(1-r)^n

Number of bacteria after 36 hour (A) = 2,000[1-0.045]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.955]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.190599333]

Number of bacteria after 36 hour (A) = 381.19866

Number of bacteria after 36 hour (A) = 381 (Approx)
