Addition of fractions with unlike denominators: 3/10 + 1/6 = 7/15
Subtraction of fractions with unlike denominators: 7/8 - 5/6 = 1/24
<u>Step-by-step explanation</u>:
"Unlike denominator" is said to have different numbers in the denominator.
- Change the unlike denominators to like denominators by finding the least common multiple (LCM) of the denominators.
- Now multiply the numerator and denominator with same number that gives the LCM in the denominator.
- Add or subtract the numerators according to the operator given, but do not perform any operation in the denominators.
<u>Addition of fractions with unlike denominators</u>:
⇒ Add 3/10 and 1/6.
⇒ Taking LCM 2 |<u>10 6</u>
<u>|5 3 </u>
⇒ The LCM is 253 = 30.
⇒ 3/10 + 1/6 = (33)/(103) + (15)/(65)
= 9/30 + 5/30
= 14/30 = 7/15
<u>Subtraction of fractions with unlike denominators</u>:
⇒ Subtract 7/8 and 5/6.
⇒ Taking LCM 2 <u>|8 6</u>
<u>|4 3 </u>
⇒ The LCM is 243 = 24.
⇒ 7/8 - 5/6 = (73)/(83) + (54)/(64)
= 21/24 - 20/24
= 1/24
Hahah PHILSWIFT I answered first
Answer:
- It is a reduction with a scale factor between 0 and 1.
- It is an enlargement with a scale factor greater than 1.
Step-by-step explanation:
1. Dilation is defined as a transformation of an image in which the size on this image changes but its shape does not change.
2. In dilation, to obtain the new dimensions of the image you must multiply the dimensions of the original image by a number called "Scale factor".
3. When the scale factor is greater than 1 it is an enlargement and when this is between 0 and 1, it is a reduction.
Answer:
17.39%
Step-by-step explanation:
We can summary the question:
- Probability of students using Google chrome= 0.49
- Probability of students using other browsers = 0.51
So the probability that you need to pick 7 students to find 2 students using Google Chrome is:
P(G) = * ()() = 21*0.2401*0.03 = 0.1739 = 17.39%
