Question

please answer....to this maths problem....​

Answer 1

Step-by-step explanation:

8) x + 5 = 12

• x = 12-5
• x = 7
• x + 5 = 12
• 7+5=12
• 12=12

9) 14/21=_/3=6/_

Let the first blank be x.

Let the second blank be y.

Now,

Separate 14/21 = x/3 and

So,

14/21 = x/3

By doing cross multiplication,

14×3 = 21×x

x = 14×3/21

x = 2

Now,

Remove x/3,

14/21 = 6/y

By doing cross multiplication,

14×y = 21×6

y = 21×6/14

y = 9

Answer 2

$\large\frac{14}{21} = \frac{y}{3} = \frac{6}{x}$

$=>\frac{14}{21} = \frac{14÷7}{21÷7}$

$=>\large\bf\frac{2}{3}$

$=>\frac{2}{3} = \frac{6}{x}$

$=>\frac{2}{3} = \frac{2×3}{3×3}$

$=>\large\bf\frac{6}{9}$

$\bf\frac{14}{21} = \bf\frac{2}{3} = \bf\frac{6}{9}$
