"她大约四十岁。"

Translation: She is approximately forty years old.

Why is this in Weather 2?

[Imnuts7]

Most likely that Duo is trying to teach you more applications of 大约.

[grippygecko]

I got this as an audio exercise with no audio. I had to guess what the sentence might be. Lucky for me I guessed rightly.

[PengXu14]

Is it just me? Or does the "approximately" sound kind of twisted in there?

[ZLove]

I used "roughly" instead of "around". My dictionary says its ok.

[CraigSkeel]

Yes, "roughly", "around", and "about" all are ok here.

[hendri21st]

what about 大概?

[SimonWhite1]

Use 大约 for approximating numbers. They talk about it in the tips for this lesson. 大概 seems more for use with situations e.g. 他大概不会来 He probably won't come.

I thought 岁 was only for low number ages (children). Is it really used for age 40?

[SimonWhite1]

Perhaps saying she's a big kid? :-D
