Un embalse estaba lleno a finales del mes de mayo. En el mes de junio se consumieron 3/10 de sus reservas y a finales de julio solo quedaba la mitad. ¿Qué fracción del embalse se consumió durante el mes de julio?

The English translation of the question is

A reservoir was full at the end of May. In the month of June 3/10 of its reserves were consumed and at the end of July only half remained. What fraction of the reservoir was consumed during the month of July?

1/5 of the Reservoir will be consumed in the month of July.    

Step-by-step explanation:

We are given

Full reservoir at the end of month May. In the month of June 3/10 of the reservoir was consumed.

Amount present in the Reservoir at the end of the month June will be = 1 -3/10

                                                                                                          = 7/10

Now this 7/10 of the Reservoir will be used for the next month which is July

It is given that at the end of July only 1/2 of the Reservoir is remained that means the amount that was left at the end of the Month June will be used for the month July. So the amount consumed in the month of July will be

    Amount consumed  =  7/10 - 1/2

                                     = 2/10 = 1/5

Therefore 1/5 of the reservoir will be consumed in the month of July.    

ian gone lie this got me confused

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
