Answer 1

Answer:

1. The smallest 3 digit number is 100. It's prime factorization is 2×2×5×5.

2.  -2,-1

3. The sum of HCF and LCM of 45, 60 and 75 is 915.

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 75 are: 1, 3, 5, 15, 25, 75

∴ The greatest common factor is 15.

45 = 3 × 3 × 5

60 = 2 × 2 × 3 × 5

75 = 3 × 5 × 5

LCM(45, 60, 75)

= 2 × 2 × 3 × 3 × 5 × 5

= 900

∴ The least common multiple is 900.

The sum of HCF and LCM of 45, 60 and 75 is = 15 + 900 = 915.

4. My guess is that -6.3 would be at least one, as the absolute value of a number is how far away it is from zero. Ex; -2 is still 2 units away from zero, just as 2 is 2 units away from zero. So both's absolute value would be 2

5. To convert 57/7 into mixed fraction

We have to do- 57/7= 8 whole 1/7

6.  

No:of days she ran=3 days

Distance ran per day=13km

Distance ran in 3 days=3×13

=39km

1km=1000m

39km=39×1000

=39000m

7.

(17×71)−(3×71)71×71

=1207−2135041

=9945041

994÷715041÷71=1471

Therefore:

1771−371=1471

8. Pictograph

a pictorial representation of statistics on a chart, graph, or computer screen

Bar graph

bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally

10.true

The real numbers include all the rational numbers, such as the integer and the fraction,

and all the irrational numbers, an irrational algebraic number).

Included within the irrationals are the transcendental numbers,  

Then all rational number includes in real number  

Then statement every rational number is a real number

Answer 2

Answer:

1. 101 and 2,3,5,7,11
2. -2, -1
3. Yes it is
4. |334|=334 and |-334|=334
5. 8 1/7
6. 4 days
7. 14/71
8. A pictograph uses pictures as the key and a bar graph is better for comparing larger changes in data
9. 2
10. true- ratio can be written in fraction form with denominator and numerator

Step-by-step explanation:

11 and 101 is not divisible by any of the prime numbers 2,3,5,7,11.

∴ 101 is a prime number.

101 is the smallest 3-digit prime number.

2. successor is a number that succeeds another number/ comes after the given number

3. 45+60=105. 105/15=7, therefore 15 is a factor of 105. Factors of 105: 1, 3, 5, 7, 15, 21, 35, 105

5. convert improper fraction into mixed fraction: the denominator 7 can go into the numerator 57 how many times? it can go in 8 times or you can say whats 57/7? 8*7=56 which is 1 less than 57 and because the remainder left to get to 57 is 1, that will go above the denominator 7. 8 1/7

6. i wasnt sure about this one but its 4 days because 1/4+1/4+1/4+1/4=1 and 1/4*4=1

7. 17-3=14, the denominators are the same so 14 over 17
