Answer:

A) 21/7, or 3

B) 36/5, or 7 1/5

C) 35/25, or 1 15/25, or 1 3/5

D) 54/12, or 4 6/12, or 4 1/2

Step-by-step explanation:

8/7 plus 13/7. You add the numerators (the numbers on top) together. That makes 21. The denominator (the numbers on bottom) stays the same. So it would be 21/7. 7 fits into 21, 3 times.

8/7 más 13/7. Agrega los numeradores (los números en la parte superior) juntos. Eso hace 21. El denominador (los números en la parte inferior) permanece igual. Entonces sería 21/7. 7 encaja en 21, 3 veces.

8/7 plus 13/7. Vous ajoutez les numérateurs (les chiffres du haut) ensemble. Cela fait 21. Le dénominateur (les chiffres du bas) reste le même. Donc, ce serait 21/7. 7 correspond à 21, 3 fois.

8/7 plus 13/7. Quarum numeratores addere (supra de numero) una. 21. Quod facit denominator est (per numeros in fundo) manebit. Ita esset 21/7. Vicium, in VII XXI, III tempora.

a) 8/7 +13/7: denominador es el mismo asi que nada mas sumas los numeradores. Respuesta 21/7 o 3

b) 18/25 + 17/25: lo mismo denominador es el mismo asi que nada mas sumas los numeradores. Respuesta 35/25 o 1 10/25

c) 9/3 + 21/5: factor en comun de los denominadores 15. 9*3=21  y 21*3=62 asi que 21/15 + 62/15 . Respuesta 83/15 o 5 8/15

d) 7/12 + 14/4: factor en comun de los denominadores 12. 14*3=42 asi que 7/12 + 42/12. Respuesta 49/12 o 4 1/12

Select yes or no to indicate whether a zero must be written in the dividend to find the quotient
neonofarm [45]

Answer:

2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No

Step-by-step explanation:

We have that when two numbers are divided, they can be written in the form \frac{p}{q}, where p is the dividend and q is the divisor.

Now, when we divide 5.2 by 8, we can write \frac{5.2}{8}

Also, the division 3.63 by 3, can be written as \frac{3.63}{3} = 1.21

Further, when we divide 71.1 by 3, we can write \frac{71.1}{3} = 23.7

We can see that above divisions are easy divisions and do not require to write any type of 0 in the numerator.

Moreover, when we divide 2.25 by 0.6, we can write \frac{2.25}{0.6} = \frac{2.25\times 10}{6}.

So, we get that in the last division, we need to write a zero in order to multiply the numerator with 10 for easy division.

Hence, 2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No
