Answer:

Conversion a mixed number -3 1

2

to a improper fraction: -3 1/2 = -3 1

2

= -3 · 2 + (-1)

2

= -6 + (-1)

2

= -7

2

To find new numerator:

a) Multiply the whole number -3 by the denominator 2. Whole number -3 equally -3 * 2

2

= -6

2

b) Add the answer from previous step -6 to the numerator 1. New numerator is -6 + 1 = -5

c) Write previous answer (new numerator -5) over the denominator 2.

Minus three and one half is minus five halfs

Conversion a mixed number -1 1

4

to a improper fraction: -1 1/4 = -1 1

4

= -1 · 4 + (-1)

4

= -4 + (-1)

4

= -5

4

To find new numerator:

a) Multiply the whole number -1 by the denominator 4. Whole number -1 equally -1 * 4

4

= -4

4

b) Add the answer from previous step -4 to the numerator 1. New numerator is -4 + 1 = -3

c) Write previous answer (new numerator -3) over the denominator 4.

Minus one and one quarter is minus three quarters

Multiple: -7

2

* (-5

4

) = -7 · (-5)

2 · 4

= 35

8

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(35, 8) = 1. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - minus seven halfs multiplied by minus five quarters = thirty-five eighths.

Unary minus: -7

2

= -7

2

Subtract: the result of step No. 4 - (-17

4

) = -7

2

- (-17

4

) = -7 · 2

2 · 2

- (-17)

4

= -14

4

- (-17

4

) = -14 - (-17)

4

= 3

4

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 4 = 8. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - minus seven halfs minus minus seventeen quarters = three quarters.

Compare: the result of step No. 3 = the result of step No. 5 = 35

8

= 3

4

= 35

8

vs 3

4

= 35

8

vs 3 · 2

4 · 2

= 35

8

vs 6

8

= 35 vs 6 = No

In the United States, there are 59 different species of mammals that are endangered,
jolli1 [7]

Given Information:

Number of endangered mammal species = 59

Number of endangered bird species = 75

Number of endangered fish species = 68

Required Information:

Probability of either a  mammal or a fish = ?

Answer:

P(mammal or fish) = 127/202 = 0.6287 = 62.87%

Step-by-step explanation:

We want to randomly select one animal and find out the probability of either a mammal or a fish.

The total number of endangered species of animals is given by

Total animals = mammal species + bird species + fish species

Total animals = 59 + 75 + 68  = 202

The probability of selecting a endangered mammal is

P(mammal) = no. of endangered mammal/total no. of endangered animals

P(mammal) = 59/202

The probability of selecting a endangered fish is

P(fish) = no. of endangered fish/total no. of endangered animals

P(fish) = 68/202

Finally, the probability of selecting either a mammal or a fish is

P(mammal or fish) = 59/202 + 68/202

P(mammal or fish) = 127/202

P(mammal or fish) = 0.6287

P(mammal or fish) = 62.87%

FIRST PERSON WHO ANSWERS THIS WILL BE BRAINLIEST
djverab [1.8K]

Answer:

2.- 100

Step-by-step explanation 1:

\frac{7}{25} + \frac{3}{4} = \frac{28}{100} + \frac{75}{100} = \frac{103}{100}

↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.

Step-by-step explanation 2:

\frac{(7 * 4) + (3 * 25)}{4 * 25} = \frac{28 * 75}{100} = \frac{103}{100}

↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Hope it helped,
