Q8) ??
The difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
Step-by-step explanation:
First, to make it easier to subtract, let's change these numbers to improper fractions.
4 5/7 = 33/7
1 3/4 = 7/4
Now, we have to find the LCM (least common multiple) between 4 and 7.
4- 4, 8, 12, 16, 20, 24, 28, 32
7- 7, 14, 21, 28, 35, 42, 49
As you can see, the LCM is 28. So, lets change these fractions to have a denominator of 28.
33*4/ 7*4 = 132/ 28
7*7/ 4*7 = 49/ 28
>>132 - 49 = 83
So, the difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28

A
Answer with explanation:
1.
Let a, and b be two numbers between 20 and 5 , which is in geometric progression.
So,the series is as Follows =20 , a, b, 5
Common ratio
[tex]=\frac{\text{Second term}}{\text{First term}}[/tex]
[tex]\frac{20}{a}=\frac{a}{b}=\frac{b}{5}\\\\b^2=5 a---(1)\\\\a^2=20 b\\\\\frac{b^4}{25}=20 b-----\text{Using 1}\\\\b^3=500\\\\b=(500)^{\frac{1}{3}}\\\\b=5\times (4)^{\frac{1}{3}}\\\\5a=25\times (4)^{\frac{2}{3}}\\\\a=5\times (4)^{\frac{2}{3}}[/tex]

⇒Sin (2.4)=Sin(2+0.4)
⇒Sin 2 ×Cos (0.4)+Cos 2 × Sin (0.4)
⇒Sin (A+B)=Sin A×Cos B+Cos A×Sin B
