Find the two numbers the quotient is between. Then estimate the quotient. 75 divided by 4
Liula [17]

Answer:

<em>The quotient will be between 18 and 19.</em>

<em>Estimated quotient will be 18.75</em>

Step-by-step explanation:

The closest number to 75 which is divisible by 4 and <u>less than 75</u> is :  72  and

the closest number to 75 which is divisible by 4 and <u>greater than 75</u> is :   76

Now,  72 \div 4= 18 and 76\div 4= 19

That means, the quotient for (75\div4) will be between 18 and 19.


As, 75 is 1 less than 76, so the quotient will be \frac{1}{4} or 0.25 less than 19.

So, the quotient will be:  19-0.25= 18.75

Salsk061 [2.6K]
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
