The smartest person can only help with the method please help <br> 3 1/4 divided by 2
nevsk [136]

Answer:

13/8 = 1 5/8

Step-by-step explanation:

first make 3 1/4 into an improper fraction

3 1/4 = (3*4+1)/4 = 13/4

13/4 /2

we know that dividing by a number is multiplying by its reciprocal, so

(13/4)/2 = 13/4 * (1/2)

multiply the numerators together, and multiply the denominators together

13/4 * (1/2) = (13*1)/(4*2) = 13/8 = 1 5/8

Mrs Rivas bought a can of paint he used 3/8 of paint and 1/4 he also used some for a birdhouse and had 1/8 of paint left how muc
Degger [83]

Answer:

The amount of paint used in the  birdhouse = (1/4) of paint

Step-by-step explanation:

The amount of paint used in first go = 3/8

The amount of pain used in second go = 1/4

The amount of paint used in bird house = k

The amount paint left = 1/8

Now, according to the question:

Paint used in ( First go + second go + Birdhouse) + Paint left = 1 can Paint

⇒\frac{3}{8}  + \frac{1}{4} + k + \frac{1}{8}    = 1\\\implies \frac{3 + 1(2) + 1}{8} + k = 1\\ \frac{6}{8} + k = 1 \\\implies k = 1 - \frac{6}{8}  = \frac{8-6}{8}  = \frac{2}{8}  = \frac{1}{4} \\\implies k = \frac{1}{4}

or, The amount of paint used in the  birdhouse = (1/4)
