Answer 1

Answers :

Part A = $\texx{17.5 \: \%}$

Part D = $\texx{56 \: \%}$

Part E = $\texx{112.5 \: \%}$

Step-by-step explanation

Question : Express the first as the percentage of second

a) 175 ml , l

》To express them, we have to convert them in like terms

》175 ml = 175 ml

》1 l = 1000 ml [1l = 1000 ml]

Setting up an equation,

$\frac{175}{1000} \: \times \: 100$

After Cancellation...

17.5 %

Hence, 17.5 % is the expressed fraction of part A.

Part D) 80 cents , $1.44

》Convert them to like terms

》80 cents = 80 cents

》$1.44 = 144 cents [1 dollar = 100 cents]

Setting up an equation,

$\frac{80}{144} \: \times \: 100$

After Cancellation...

55.555...

Now rounding off,

56 %

Hence; 56 % is the expressed fraction of part d

Part E,

》Convert into like terms.

》225 mm = 225 mm

》20 cm = 200 mm [1 cm = 10 mm]

Setting up an equation,

$\frac{225}{200} \: \times \: 100$

After Cancellation...

112.5 %

Hence; 112.5 % is the expressed fraction of part d

Answer 2

$\underline{\bold{Answer}}$

$\underline{\underline{Question\:No.5}}$

a) 175ml = 175ml

We know that,

1l = 1000ml.

According to the question,

$\dfrac{175}{1000}\times 100$

= 17.5 %

So the answer of this is 17.5%.

______________________________

c) 225mm = 225mm.

We know that,

1cm = 10mm

So, 20cm = 200mm.

According to the question,

$\dfrac{225}{200}\times 100$

= $\dfrac{225}{2}$ = 112.5%.

So the answer of this one is 112.5%.

_______________________________

d) 80 cents = 80cents.

We know that,

$1 = 100 cents.

So , $1.44 = 144 cents.

According to the question ,

$\dfrac{80}{144}\times 100$

= $\dfrac{500}{9}$ = 55.55%.

The answer of this part is 55.55%.
