Please answer the questions ​

Answer 1

Answer:

1 . 5.25

Step-by-step explanation:

100 - 94.75 = 5.25

Answer 2

Answer:

i) Let the unknown number be x.

x+94.75=100

➺x= 100-94.75

➺x= 5.25

ii) ★We know that:

1 kg= 1000g

★Solution:

$5 \frac{1}{4} \\ \\ ➺ \frac{21}{4}kg$

$➺ \frac{21}{ \cancel{4}} \times \cancel{1000} \: ^{ \: 250} \\ \\➺ 21 \times 250 \\ \\ ➺5250g$

iii) ★We have:

The cost of 1kg sugar is Rs.12.50

★Solution:

The cost of 1kg sugar is. = Rs.12.50

The cost of 5kg of sugar is= Rs.12.50×5 = Rs.62.5

Therefore, The cost of 5kg of sugar is Rs.62.5

iv) Let the unknown number be x.

x+ 1889.75=2600

➺x= 2600-1889.75

➺x= 710.25

Therefore, The another number is 710.25

v) 3 hour= 3×60 = 180min

$\frac{1}{10} \: of \: an \: hour \: i.e. \: in \: min.$

$➺ \frac{1}{1 \cancel{0}} \times 6 \cancel{0} \\ \\ ➺1 \times 6 \\ \\ ➺6min$

So,

(180+6)min = 186min

Therefore, The answer is 186min.

vi) Expand form of 482.305 is

$400 + 80 + 2 + \frac{3}{10} + \frac{5}{1000}$

vii)

$8 \frac{2}{5} \\ \\ ➺ \frac{42}{5}$

Therefore, There are 42 fifths.

viii) Factor of 30:-1,2,3,5,6,10,15,30

Factor of 45:- 1,3,5,9,15,45

Common factors are: 5 and 15

Therefore, The answer is 5 and 15.

ix) (120+90)=210

Now,

1000-210 = 790

Therefore, The answer is 790.

x) 4.25+2.35+7.5 = 14.1

Therefore, The answer is 14.1
