Answer:

\huge\boxed{\bf\: \frac{93}{20}=4.65}

Step-by-step explanation:

3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }

Now,

3 \frac { 1 } { 4 } \\= \frac{4 * 3+1}{4}\\= \frac{13}{4}

Then,

1 \frac { 2 } { 5 }\\= \frac{1* 5+2}{5} \\= \frac{7}{5}

So,

3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }\\= \frac{13}{4}+\frac{7}{5}\\ \\\mathrm{LCM = 20}\\\\= \frac{65}{20}+\frac{28}{20} \\=\boxed{\bf\: \frac{93}{20}=4.65}

Solve the math problem
Nadusha1986 [10]

<u>Answer:</u>

Below!

<u>Explanation:</u>

Exponents are small numbers that defines how many times does the base needs to multiply itself. Two exponents can also be classified in words. 'Squared' defines a number multiplying itself two times. 'Cubed' defines a number multiplying itself three times. If there is a zero as the base's exponent, this means that the result will always be 1. Now, let's solve all the problems together.

  • 2¹ = 2
  • 3⁵ = 3 x 3 x 3 x 3 x 3 = 243
  • 4³ = 4 x 4 x 4 = 64
  • 6⁴ = 6 x 6 x 6 x 6 = 1256
  • 7⁴ = 7 x 7 x 7 x 7 = 2401
  • 1⁶ = 1 x 1 x 1 x 1 x 1 x 1 = 1
  • 8² = 8 x 8 = 64
  • 2³ = 2 x 2 x 2 = 8
  • 4⁴ = 4 x 4 x 4 x 4 = 256
  • 10³ = 10 x 10 x 10 = 1000
  • 12² = 12 x 12 = 144
  • 5⁴ = 5 x 5 x 5 x 5 = 625
  • 6² = 6 x 6 = 36
  • 3⁶ = 3 x 3 x 3 x 3 x 3 x 3 = 729
  • 7³ = 7 x 7 x 7 = 343
  • 2⁴ = 2 x 2 x 2 x 2 = 16
  • 11⁰ = 1
  • 4³ = 4 x 4 x 4 = 64
  • 1¹² = 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 = 1

Simplest form of 2/10
slega [8]
To simplify fractions, all you have to do is divide both the numerator and the denominator by the greatest common factor of both integers.

In this case, the greatest common factor of 2 and 10 is 2.

2/2=1
10/2=5

So, 2/10 in its simplest form is 1/5.
