Ingrid Is Making A Toy Car. The Toy Car Is 5 10 \frac{5}{10} 10 5 ​ Meter High Without The Roof. The Roof Is 18 100 \frac{18}{100} 100 18 ​ Meter High. What Is The Height Of The Toy Car With The Roof? Choose A Number From Each Column To Complete An Equation

Understanding the Problem

Ingrid is making a toy car, and we need to find the total height of the toy car with the roof. The height of the toy car without the roof is given as $\frac{5}{10}$ meter, and the height of the roof is $\frac{18}{100}$ meter. To find the total height of the toy car with the roof, we need to add the height of the toy car without the roof and the height of the roof.

Breaking Down the Fractions

To add the fractions, we need to have the same denominator. The least common multiple (LCM) of 10 and 100 is 100. We can convert the fraction $\frac{5}{10}$ to have a denominator of 100 by multiplying the numerator and denominator by 10.

$\frac{5}{10} = \frac{5 \times 10}{10 \times 10} = \frac{50}{100}$

Adding the Fractions

Now that we have the same denominator, we can add the fractions.

$\frac{50}{100} + \frac{18}{100} = \frac{68}{100}$

Simplifying the Fraction

We can simplify the fraction $\frac{68}{100}$ by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 4.

$\frac{68}{100} = \frac{68 \div 4}{100 \div 4} = \frac{17}{25}$

Conclusion

The total height of the toy car with the roof is $\frac{17}{25}$ meter.

Choosing Numbers from Each Column

To complete the equation, we need to choose a number from each column. Let's choose 17 from the first column and 25 from the second column.

$17 \div 25 = 0.68$

Interpreting the Result

The result of the equation is 0.68, which represents the total height of the toy car with the roof in decimal form.
